Going through chemotherapy provides me with a different point of view. The elders with good intentions said "blood fragments are your choice (a very old and socially retarded elder who disowned his own kids, not spoken with them for twenty years bluntly said "blood-fragments are against Jehovah's law, it's a sin and no different from a total blood transfusion") with a few outspoken ones providing additional confusion at a very troubling time.
To see how fragmented each Kingdom Hall is, "one say's you can and one say's you can' and others say "Dont Ask, Don't Tell" I feel pity for this sister, until you are placed with a life and death decession on Blood, it's best to keep the elders out of this!
